Title: Screwless spring joint for spectacles, spectacle frame and spectacles
Inventor: SHONO TAKESHI
IPC: G02C5/22
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a screwless spring hinge for spectacles based on the entirely different operating principle while adopting the constitution resembling the prior art, a spectacle frame having this spring joint and spectacles. SOLUTION: When a revolving shaft 13 of the spring joint is successively rotated αt from a reference position, the width Wt in the direction orthogonal with the reference plane of the revolving shaft 13 is spread from a width Wo, legs 23 and 25 of a bearing 21 are opened. Since the opening of the legs 23 and 25 is elastic deformation, the revolving shaft 13 in contact with the leg 25 at the segment perpendicular to the plane of the figure passing a point A is subjected to elastic repulsion F from the leg 25 tending to close. The revolving shaft 13 eventually receives the force of the βdirection reverse to the αdirection by the component of force F2 in the tangential direction of the elastic repulsion F and tends to restore the home position. Conversely speaking, the revolving shaft 13 is so energized as to be rest to the reference position.
